Sjunct populations in New York. Allocapnia PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21323101 pechumani Ross Ricker, 1964. Our records demonstrate this uncommon species to inhabit medium sized streams (Fig. 7) within the glaciated northeastern corner with the state (Fig. 20). Adults occur in the course of February and March (Table three). Allocapnia pechumani can also be recognized from Pennsylvania northeast to New Brunswick. Allocapnia pygmaea (Burmeister, 1839). This species occurs in seven little streams (Fig. 7) in southern and northeastern Ohio (Fig. 20). Our data suggest a mid-February via March emergence (Table 3). Allocapnia pygmaea PD 151746 happens over substantially of eastern North America.Atlas of Ohio Aquatic Insects: Volume II, PlecopteraAllocapnia recta (Claassen, 1924). This species inhabits compact streams (Fig. 7) across the majority of the state (Fig. 20). DeWalt et al. (2005) and DeWalt and Grubbs (2011) also report it from some of the largest streams in Illinois and Indiana, respectively. This really is the earliest emerging snowfly, collected as early as mid-November, but continuing through March (Table three). Allocapnia recta happens all through considerably of eastern North America west from the Mississippi River. Allocapnia rickeri Frison, 1942. This species inhabits little streams (Fig. 7) across the majority of the state (Fig. 20). Adult presence encompasses January through April (Table 3). The species happens broadly across eastern North America. Allocapnia smithi Ross Ricker, 1971. This is certainly one of the rarest stonefly species inhabiting eastern North America. One male and one particular female are recognized from two compact ravine streams in Warren County (Figs 7, 20). Each specimens had been collected in mid-February (Table three). Allocapnia smithi is restricted to unglaciated regions of Illinois, Indiana and Ohio, and in both Kentucky and central Alabama. Allocapnia vivipara (Claassen, 1924). This species occurs in a broad selection of stream sizes (Fig. 7) across all of Ohio (Fig. 20). Adults emerge as early as mid-December, persisting through April (Table 3). Allocapnia vivipara exhibits the widest distribution of any Allocapnia in eastern North America. Allocapnia zola Ricker, 1952. This species occurs in modest streams (Fig. 7) in 3 adjacent counties of your Hocking Hills region of southern Ohio (Fig. 20). Adults take place from January by means of April (Table three). All round, A. zola ranges from Ohio to Appalachian Kentucky, northeastward to New Brunswick. Paracapnia angulata Hanson, 1961. This species inhabits mainly tiny, cold streams (Fig. 7), exhibiting a broad, but patchy distribution across the state (Fig. 20). New records in the tributaries of Ohio Brush Creek, Edge of Appalachia Preserve, in Adams County recommend that the species is much more widely distributed in spring fed streams of southwestern Ohio than at the moment identified. Depending upon latitude, adults emerge in January, persisting by way of April (Table three). This species is extensively distributed across eastern North America.Leuctridae. NeedlefliesLeuctra alexanderi Hanson, 1941. This species is rare, occurring in only 3 tiny streams (Fig. eight) within the eastern half on the state (Fig. 21). Adult presence extends from midMay by means of mid-June (Table 3). The distribution of this species encompasses the central and southern Appalachian Mountains from Tennessee north to Pennsylvania, into eastern Ohio. Leuctra duplicata Claassen, 1923. This species occurs in two tiny (Fig. 8), closely adjacent streams in Ashtabula County (Fig. 21). Adults occur in early June (Table 3). ThisDeWalt R et al.species is most likely far more abundant i.
